chore: update package.json scripts and add new dependencies

- Replaced the test script to run test-providers.js.
- Updated the build script to run build-simple.js.
- Added new scripts for development: dev, dev:build, watch, watch:dev, dev:auto, and auto.
- Updated start script to build and then run the dev server.
- Added new devDependencies: concurrently, cors, express, and nodemon.
